altar rarest PICKER-STICK CHECK.

Application filed November 28, 1921 Serial No. 518,393.

To all whom it may concern:

Be it known that we, AMnnnn Massn'zand Anton BnNsoN, citizens of theUnited States, residing at Norwich, in the county of New London andState of Connecticut, have invented new and useful Improvements inPicker-Stick Checks, of which the following is a specification.

Our present invention pertains to looms and more particularly to loomsof the Draper type, and it contemplates the provision of a check throughthe medium of which the picker stick is placed under tension duringmovements of the shuttle in the shuttle box.

The invention further contemplates a check that is simple andinexpensive in constrnction and one that is well adapted to withstandrough usage.

The invention in all of its details will be fully understood from thefollowing description and claims when the same are read in connectionwith the drawings accompanying and forming part of this specification,in which Figure 1 is a side elevation of our novel tension means asapplied to a portion of a loom.

Figure 2 is a sectional view taken in the plane indicated by line 2-2 ofFigure 1 and showing the left hand tension means.

Figure 3 is a sectional view taken in the plane 3-?) of Figure 1 andshowing the right hand tension means.

Figure 4 is a sectional view taken in the plane indicated by line 44: ofFigure 1 and showing the left hand tension means and its relation to itscomplementary picker stick.

Figure 5, is a sectional view taken in the plane indicated by line 55 ofFigure 1 and showing the relation of the right hand tension means andits complementary picker stick.

Similar numerals of reference designate corresponding parts in all theviews of the drawings.

The right and left hand picker sticks 1 as well as the picker 2 thereofare of the ordinary well known construction and as illustrated areproperly positioned with respect to the loom lay A. Mounted on andadapted to move with respect to the lay within the box 4:, is theshuttle 3.

Our novel left hand tension 5 is bolted or otherwise secured to the layA and adapted to be secured in adjustable manner thereto. It will bemanifest that the tension means is adapted for connection to variousstyles of lays as the case may be.

The tension means 5 comprises a body 69 provided with the bent endportions 8 that abut the lower surface of the lay and assist inretaining the body 5 in rigid manner on the lay A. Formed integral onthe portion 5 is a hanger 7 that is bent parallel with respect to thebent end portions 8, at its lower end as indicated'by- 9.

The construction so far set forth is duplicated on, the opposite side ofthe lay as shown in Figure 4 and thetwo sections 5 are bolted to the layby the one bolttS.v Provided on the bent portion 9 ofhangers 7-areorifices 9 through which pass boltsor other means 10 and the saidbolts also enter parallel arms 11 that extend beyond the outer limit ofmotion of the picker stick and secured at their outer ends toeach otherby the bolt 12.

Interposed between the parallel arms 11 on the bolt 12 are washers 12 ofleather or other suitable material that receives the thrust and checkthe movement of the picker stick.

The tension members 11 are formed of wood or other suitable material andhence the constant thrust of the picker stick will subject the tensionmembers to strain beyond their ability to withstand the same.

Moreover the construction of the tension means and the washer interposedon the bolt 12 will assist in materially forcing in a quick manner thepicker stick to cause same to rebound to the right after striking thewashers.

Secured on the opposite end of the lay is the right hand tension meansthat comprises the body portion 13 bolted or otherwise arranged on thelay as indicated by 14 and the body portion 13 is provided with the bentends 16 that bear on the underside of the lay for the same purpose asthe portions 8 of member 5.

The body portion 13 is provided with the integral hanger portion 15having a lower bent end 17 provided with the orifice 18 that receives abolt 19 which in turn passes through one end of the parallel arms 20 ofwood, or other similar material that are identical in construction toarms 11, above referred to. Arranged parallel with arms are arms 21 andsaid arms20 and 21 are I s secured at one end to each other by bolt 22.

Interposed on the bolt 22, between the series of arms 20 and 21 arewashers 12 of leather or suitable cushioning material adapted to receivethe thrust of the picker stick and secured to the free ends of arms 21is a head portion that is held in proper position by means of the bolt24.

A bolt for the purpose of reinforcing the head passes through asindicated by 23.

In the practical use of the invention it will be manifest that theoutward thrust of the picker sticks against the washers of the bolts isto limit the motion of the sticks during operation of the loom. It willalso be seen that said Washers will assist in causing a quick rebound ofthe picker sticks and be cause ofthe fact that the arms 11 20 and 21wooden arms for the well known leather strap at present in use, assuresa longer life and even and steady operation of the loom.

Having described our invention, what we claim and desire to secure byLetters-Patent,

1. In check mechanism, the combination of a loom, a body portion havinga head secured to the loom, parallel spaced arms secured to the body, abolt for securing the arms to each other, washers arranged on the boltbetween the arms, a head secured on the arms and means for securing thehead to said arms.

2. In means for the purpose set forth, the combination of body membersadapted to be secured to the lay of a loom, downwardly dependingportions secured to the body members, abutments "formed on the body,members, arms adapted to receive a picker stick therebetween, hangersdepending from the body members, arms secured a the hangers, and a headsecured to the arms.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses. I

AMEDEE MASSEY.
